Since David Snowden and Cynthia Kurtz published in 2003 their seminal work “The New Dynamics of Strategy: sense-making in a complex-complicated world”, the Cynefin framework for decision making has been widely adopted. Today, there are hundreds of sites in Internet explaining the framework. Then... why another presentation on the topic? Simply because it seems that most of those sites skip the first half of the paper. And this is really a shame because they are missing: • Bram Stoker and the undead • Marines playing stock market games and stock traders playing war games • West Point graduates trying to emulate Arnold Schwarzenegger in the movie Kindergarten Cop... well... sort of! Join me in this unusual journey across centuries, from the moment the most renowned scientific book in history is published to the time when managers started believing that if the universe could be explained, then it should be possible to have their projects accurately estimated.
